Abstract
The invention discloses a dipping type evaporative cooling transformer comprising a box body, an iron core, a winding, a condenser, a steam rising pipe and a condensation liquid dropping pipe. Condensation liquid is stored in the box body, the iron core and the winding are dipped in the condensation liquid, the bottom of the box body is provided with a condensation liquid inlet, and the top of the box body is provided with a steam outlet. The condenser is arranged above the box body in an inclined mode, the inclined bottom of the condenser is provided with an inlet and an outlet, and the horizontal height of the outlet is lower than that of the inlet. The condensation liquid dropping pipe is communicated with the condensation liquid inlet in the bottom of the box body and the outlet in the bottom of the condenser. The steam rising pipe is communicated with the steam outlet in the top of the box body and the inlet in the bottom of the condenser. The dipping type evaporative cooling transformer is simple in structure, low in cost, convenient to maintain, non-flammable, and not prone to being corroded.
Description
Technical field
The present invention relates to a kind of impregnated vapour-cooled transformer.
Background technology
In the transformer running, the winding of transformer-cabinet inside and meeting unshakable in one's determination produce loss, the heat part that loss produces has been used for promoting winding and own temperature unshakable in one's determination, another part is passed to the casing wall by transformer oil with convection current and heat conducting mode, thereby part temperatures such as the pasta of transformer and winding are raise.Can make too high aging quickening of insulating part that causes its transformer inside of winding temperature of transformer if do not take measures, insulation life shortens, and transformer can't normally move.
Evaporative cooling is as a kind of novel cooling technology efficiently, and the heat that the latent heat of vaporization when it evaporates according to coolant is taken away main equipment makes its cooling, has flexible arrangement, heat exchange efficiency height, advantage such as remarkable, safe and reliable, economic easy care of lowering the temperature.At present, transformer based on evaporation cooling technique approximately is divided into fountain, isolated and impregnated, wherein, the impregnated vapour-cooled transformer is to cool off in winding and the iron core immersion cooling fluid, generally with the mixed liquor of tetrachloro-ethylene and transformer oil as cooling fluid, but this medium has inflammability and corrosivity.And, the present most complex structure of impregnated transformer, inhomogeneous cooling is even, and cost and maintenance cost are higher.
Summary of the invention
The object of the present invention is to provide a kind of impregnated vapour-cooled transformer, simple in structure, cost is lower, and is easy to maintenance, and nonflammable, also not perishable.
The technical scheme that realizes above-mentioned purpose is:
A kind of impregnated vapour-cooled transformer comprises casing, iron core and winding, and described impregnated vapour-cooled transformer also comprises condenser, vapor uptake and condensate descending, wherein:
Described memory box has condensate liquid, and described iron core and winding are immersed in the described condensate liquid;
Described bottom half has a condensate liquid import, and the top has a steam (vapor) outlet;
Described condenser is in tilted layout above described casing, and the bottom surface that this condenser tilts has an import and an outlet, and the level height of outlet is lower than the level height of import;
Described condensate descending is connected the condensate liquid import of described bottom half and the outlet of described condenser bottom surface;
Described vapor uptake is connected the steam (vapor) outlet at described casing top and the import of described condenser bottom surface.
Above-mentioned impregnated vapour-cooled transformer, wherein, described condensate liquid closes liquid for the fluorine carbonization.
The invention has the beneficial effects as follows: the present invention has nonflammable and uncorruptible character owing to use the fluorine carbonization to close liquid as cooling fluid.Simultaneously, the present invention utilizes difference in height and transpiration-cooled rule, simple designs structure, cost is lower, and is easy to maintenance, possesses high practicality.
Description of drawings
Fig. 1 is the structural representation of impregnated vapour-cooled transformer of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
See also Fig. 1, impregnated vapour-cooled transformer of the present invention comprises casing 1, iron core 2, winding 3, condenser 4, vapor uptake 5 and condensate descending 6, wherein:
Casing 1 internal memory contain condensate liquid, iron core 2 and winding 3 are immersed in the condensate liquid; In the present embodiment, condensate liquid closes liquid for the fluorine carbonization;
Condensate descending 6 is connected the condensate liquid import 11 of casing 1 bottom and the outlet 42 of condenser 4 bottom surfaces;
Among the present invention, condensate liquid is in the heat absorption vaporization of the heater of winding 3 and iron core 2 surface, and the steam after the vaporization rises to the condenser 4 of casing 1 top by vapor uptake 5, flows out by outlet 42 after liquid is returned in condensation in condenser 4, through condensate descending 6 to casing 1, periodic duty.Therefore, utilize difference in height and transpiration-cooled rule to design the present invention, make simple in structure, with low cost.
In the present embodiment, the type of cooling of condenser 4 is water-cooled, and namely cooling water flow is realized cooling through condenser 4.
